Dropping a database

This recipe shows how you can drop a database using PowerShell and SMO.

Getting ready

This task assumes you have created a database called TestDB. If you don't have it, create the database TestDB by following the steps in the Creating a database recipe.

How to do it...

Here are the steps to drop your TestDB database:

1. Open PowerShell ISE as administrator.

2. Import the SQLPS module and create a new SMO Server Object:

   #import SQL Server module
   Import-Module SQLPS -DisableNameChecking
   
   #replace this with your instance name
   $instanceName = "localhost"
   $server = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server -ArgumentList $instanceName

3. Add the following script and run:

   $dbName = "TestDB"
   
   #need to check if database exists, and if it does, drop it
   $db = $server.Databases[$dbName]
   if ($db)
   {
         #we will use KillDatabase instead of Drop
         #Kill database will drop active connections before
         #dropping the database
         $server.KillDatabase($dbName)
   }
